I am 5 weeks post microdiscectomy L4 L5 and for the past few weeks I have been waking up early in the mornings with terrible soreness/pain in my soas muscles. Its so bad that i'm back on my pain meds. We have a new mattress, so I'm thinking that in the middle of the night i'm twisting and turning. Any advice how to manage morning pains or good sleeping positions? I hate relying on the pain meds.
